16 Claims. 1

This invention is directed to improvements in a machine or apparatus forproducing insulated shingles for use in the construction. and buildingindustry.

There is a definite and pressing need for a combination shingle havinginsulation affixed thereto in such manner that the ordinary act oflaying the shingles, either as a roofing or siding covering, carrieswith it the establishment of an underlying layer f insulation. As aconsequence, the use of insulated shingles effects a pronounced economy,and it is an object of this invention to provide a machine or apparatusfor producing insulated shingles on a mass production basis, therebyachieving further economy.

It is a further object of this invention to provide a production machinewhich operates rapidly and effectively to bring pre-cut slabs of aninsulating material into proper relation with the shingles and to unitethe same by the application of an adhesive material and with the aid ofa moderate degree of pressing.

It is another object of the present invention to provide an insulatedshingle production machine or apparatus which embodies improved meansfor processing the several parts of the final article in a simple andeffective series of operations, thereby effecting a considerable savingin labor and cost of manufacture.

It is another object hereof to provide a production machine havingimproved features of construction and operation, as will hereinafter bemore fully described.

` These and additional objects and advantages will be more specificallypointed out in the course of the detailed description relating to apresently preferred embodiment of the invention, as the same isdisclosed in the accompanying drawing, wherein:

Fig. 1Q is a fragmentary view similar to Fig. 6 showing the regulatingmeans.

Reference will now be made to Figs. l, 2 and 3 for an understanding ofthe present machine. The frame structure of the machine comprisesvertical members arranged in spaced pairs at each of the corners, sothat the front pairs of members Il) andthe rear pairs of members Il areoppositely aligned transversely of the machine. These members areconnected by suitable upper and lower transverse angle members I2 at thefront and similarly located members I3 at the rear. The frame alsoinclud-es a pair of longitudinally directed, side angle members I6 whichare transversely spaced and secured to the l respective vertical pairsof members IIJ and II in position to project forwardly of the frontmembers I0. A channel member I5 is carried on the upper surface of theinturned angle leg of each of the members I4, Iand a plate I6 spans thewidth of the machine to rest upon these channels and provide a platformupon which a stack of the shingles S (Fig. 9) may be placed. At the rearmargin of the plate I6, a vertical support means I1 is arranged tosupport the front margin of a platform I8 which extends toward the frontones 0f the vertical members I0 so that its rear margin is opentherebetween. The rear Zone of platform I8 is rigidly supported uponlaterally spaced posts I9 secured thereto and resting upon the rear zoneof the platform I6. Additional intermediate supports are provided, andare constituted by the enlarged cylindrical columns 20 arranged in apreferred spac-ed order as will appear hereinafter.

A rectangularly shaped, enlarged reservoir or open top tank 2l (Figs. 1,2 and 8) is supported along its opposite longitudinal bottom margins bythe inturned iiange legs of th-e elongate members I4. The front and reartransverse bottom margins of this tank rest upon the respectivecross-angle members I2 and I3 (Fig. 1), so that f the tank is firmly andfully supported about its bottom margins and rests in a substantiallyhorizontal position within the frame structure. This tank 2| is adaptedto contain a supply of a suitable adhesive material, usually kept atabout the level shown at A in Fig. 8. A suitable adhesive material isasphalt, and in order that it may be held in a desired iiuid condition,the tank is equipped with electrical heater strips 22 disposed along itsbottom surface. Ihe tank 2| is shown for simplicity as having thickenedwalls for aiding in the retention of heat, but ya doublewall tank withinsulation between the walls will serve as an equivalent thereof.

The open top of the asphalt reservoir or tank 2| is adapted to be closedby a conveyor platform of sectional construction, such that the loadingof the tank may be accomplished by removal of one section withoutdisturbing other sections. This platform serves as a tank cover toprotect the asphalt and as a surface for supporting the insulation slabsI (Fig. 9) during their conveyance through the machine. In Figs. -2 and8, the conveyor platform cover over the tank is comprised of a solidplate member 23 having a clear upper surface, an adjacent and removableintermediate plate member 24 having a continuous surface upon which aseries of guide rail sections 25 are secured, and a third plate member25 having a continuous rear surface portion adjacent the member 24 and aforward portion suitably cut-away or longitudinally notched to formlaterally spaced plate extensions 2`| of relatively narrow extent and apair of intermediate and spaced plate extensions 28 of relatively widerextent than the outer extension 21. This third member 26 carries aseries of guide rail sections 23, each of which is arranged inlongitudinal extension of and abutment with corresponding rail sections25 on the intermediate member 24. It can be seen in Fig. 2 that theplate member 23 overhangs the rear transverse wall of the tank 2| toprovide a suitable entrance lip 33 for the conveyor mechanism, later tobe described. The

several rail sections 25 on plate member 24' are arranged in matchedpairs identied by the oppositely directed beveled entrance faces 3|,thereby defining the entrance for each of three parallel guide-ways. Theguide-way rail sections 23 carried by the notched plate member 26 arespaced from the notch margins so that a narrow lip surface 32 remainsfor effective marginal support of the insulation slabs I which are movedthrough the guide-ways. The end portions of plate extensions 21 and 28overhang the front transverse wall of the tank 2| and are downwardlycurved to act as exit lips for the conveyor mechanism. The rail sections29 carried by these plate extensions are similarly curved for a likepurpose, as may be better seen in Figs. 4 and 5.

The conveyor mechanism associated with the above described conveyorplatform and guide rail assembly is comprised of a pair of laterallyspaced and parallel endless chain belts 33, these belts 33 have aplurality of flights attached thereto, and each of these flightsconsists of av carrier or push bar element 34 spanning the belts 33. Theconveyor belts 33 have a working span or pass across the tank 2|, asdefined by the vertically adjustable sprockets 35 carried on a commonshaft 35, the shaft 35 being mounted in suitable bearing blocks 3ladjustably carried by and between the vertical members (Fig. 2). Theopposite end or exit of this conveyor pass is defined by the fixedsprockets 38 mounted on a commonshaft 39 bearinged in fixed blocks 40carried by and between the vertical members I0. The sprockets 38 arepreferably fixed in position so that they maintain the desired path oftravel of the ight bar elements 34 over the curved lip of the plateextensions 2l and 29, see Figs. 4 and 5.

The conveyor mechanism has a pair of idler sprockets 4| (one only beingshown in Fig. 1) carried on a common shaft 42, the shaft being supportedin adjustable bearing blocks 43 carried by the vertical members l asshown. The drive for the conveyor comprises sprockets M mounted on acommon shaft l5 (Figs. 1 and 3) This drive shaft i5 is disposed in xedbearing blocks 46 carried by the vertical members l5, and one end of theshaft is extended at 4l to mount an enlarged sprocket Q8 at the outerside of the frame. The sprocket @i8 is chain connected with a poweroutput sprocket 119 (Fig. 1) of a speed reduction gear unit 55. Thereduction gear unit 50 is detachably connected with an electric motor5|, as by the coupling 52. The reduction gear 53 and motor 5| aresecured to a suitable platform 53 carried on the angle member 5i whichserves to tie together the bottom portions of members I2 and thestructural details of the machine.

The means for feeding pre-cut slabs I of the insulation material, of thecharacter indicated in Fig. 9, includes a magazine assembly M (Figs. 1and 2) which is bodily removably secured to bearing pads 55 positionedon top of the pairs of vertical members The attachment is effected (oneside only being shown in Fig. 1) by a laterally projecting wing plate 56resting on the pad 55 and xed to the side angle member 5T of themagazine M. A brace plate 58 is also used to strengthen the assembly.The magazine proper is formed of an outer casing sheet set verticallyand bent to form an open bottom, rectangular container having oppositeside walls 50, a back wall 6| and a front wall 52. As may be seen inFig. 2, the front wall 62 is notched in its lower zone to provide threesight openings 53 for observance of the loaded condition of the same.The back wall 5| is also notched in its upper zone to provide threeopenings 6 by which a stack of insulation slabs I may be placed therein.The'interior of the magazine casing is suitably divided into threecompartments by a plurality of partitions 65, so that each compartmentin which insulation slabs are placed includes a back wall loading notch64 and a front wall sight opening 33. The magazine assembly M is locatedabove the top surface of the tank cover plate 23 a distance (Fig. 1)which is slightly greater than the thickness of the insulation slabs I,whereby the stack of slabs in each compartment rest upon the plate 23,with only the lowermost one of such slabs in position to be pushed oifthe bottom of the stack. When this is done, the stack will fall bygravity to expose the next slab. It will also be observed that eachcompartment of the magazine M is aligned with one of the conveyorguide-ways (Fig. 2), whereby the insulation slabs are properlyconditioned for movement thereto.

The conveyor flight bars or carrier elements 34 are adapted to passbetween the bottom of the magazine M and the surface of plate 23 so thateach carrier 36 engages three exposed insulation slabs at one time andpushes such slabs off the bottom of the stacks for entrance at beveledfaces 3| to the guide-ways. Since the guide rails 25 and The electricalpower supply for theV motor 5| and such controls as may be required ordesired have not been shown, in order to simplify 29 lie above the planeof plates 24 and 26, there has been provided fixed cam means 66 (Figs. 1and 2) at'each side of the tank2 the cam means acting to elevate thecarrier elements 34 for subsequent sliding passage over the rails 25 and29.

Means for applying a coating of the adhesive material to each of theinsulation slabs, as the same are carried along the working pass of theconveyor by elements 34, includes spaced roller members 61 mounted on acommon shaft 68 bearinged in the tank walls such that the rollers arepartly immersed in the adhesive material andA carry a surface filmthereof during rotation. Scraper means (not shown) may be fixed in thetank 2| to regulate the thickness of the film, and other means may beemployed to clean the rollers as they reenter the body of adhesive, sothat the working surface of each roller is kept in condition. Theserollers 61 are disposed in the zone of the notches of the plate 26 (Fig.2) and have their upper surface running slightly above the horizontaltop plane of the plate 26 for positive contact with the insulationslabs. Each roller 61 presents an effective adhesive applying surfacewhich is not as wide as the Width of the insulation slabs movedthereover by an amount found to be effective in preventing the spread ofthe adhesive to the conveyor or fixed plate members. Roller operation iseffected by a drive sprocket 69 (Fig. 2) fixed on the extension 16 ofthe shaft 68, the sprocket 69 being chain driven from a sprocket 1|fixed to the extended end 12 of the conveyor sprocket shaft 39.

Means for continuously agitating the adhesive material in tank 2|comprises the shaft 13 carrying a plurality of paddle blades 1li (Figs.1, 2 and 8) which effect a continuous transfer of the more fluid stratumof adhesive near the bottom of the tank toward the upper stratum. Thisis important to maintain a uniform fluid condition of the adhesive,especially when using asphalt which tends to harden or solidify ratherrapidly. The shaft 13 has a sprocket 15 on its outer end and thissprocket is chain-connected with a sprocket 16 (Fig. 2) fixed on theroller shaft extension 10.

' In conjunction with the use of narrow rollers 61 to limit lateralspread of the adhesive, means is also provided for terminating theapplication of the adhesive at a point just prior to full or completepassage ofthe insulation slabs past the line of roller contact. Theterminating means operates to elevate or lift each slab at the propertime, thus positively breaking contact with the roller. The preferredmeans comprises a rock shaft 11 spanning the width of tank 2| and1ocated ahead of the rollers 61, as may be seen most clearly in Figs. 2,6, 1 and 10. This rock shaft 11 carries a plurality of adjustablefingers 18 arranged in pairs at the opposite end faces of each roller61. Thus, there are six such fingers 18, and each finger is movableupwardly in the space or gap formed between the roller end faces and theadjacent margins of the guide-way lip portions 32 (see Fig. 2). Eachpair of fingers 18 acts to lift one of the insulation slabs, and forthis purpose the free ends of the fingers have been adjusted to move inan arcuate path close to but at one side of the Vertical center line ofthe roller axis. The operation of the shaft 11 is made responsive tomovement of the carrier elements 34 at a predetermined point in theapproach thereof to the zone of the rollers 61. For this purpose, a pairof trigger elements 19 are pivoted at the outer side f the tank 2|(Figs. 2 and 10) 6. oni pivot pins 80. .'One end of these triggers nor-imally project above the plane of the conveyor platform (Figs. 6 and 10)so as to lie in the path of the carrier element 34. The opposite ends ofthe triggers are relatively loosely pivotally connected by pins 8| withthe crank arms 82 fixed to the opposite ends of the shaft 11. A specificshowing of one such trigger assembly is shown in Figs. 6, 7 and 10, andreference Will now be made thereto. The trigger mechanism is so mountedthat the combined weight of the fingers 18 acts to rotate the shaft 11and crank arm 82 in a direction for holding the triggers 18 in cockedposition of Fig. 6. Upon contact being established between the trigger19 and carrier element 34, it can be appreciated that the trigger willbe rotated downwardly about its pivot pin to move the crank arm 82upwardly, causing rotation of shaft 11 in an opposite direction(clockwise), such as to raise the fingers 18 (Fig. 7) sufficiently tobreak contact between the rollers and the overlying insulation slabs.Thus, the application of adhesive material to the slabs is desirablyterminated at a point just short of the trailing margin of the slabs.The trigger 19 is automatically restored to cocked position (Fig. 6)after the carrier element 34 has passed beyond it, thereby conditioningthe same for operation by each succeeding carrier element.

Referring particularly to Figs. 1, 3, 4 and 5, it can be seen that theplane of the conveyor guide platform across the top of tank 2| islocated above the plane of the shingle supporting platform I8, and thetwo levels are separated by a gap or space which permits the carrierelement 34 to pass downwardly through the gap on its return or idle passto the zone of the magazine M. A swingable or rockable mechanism hasbeen provided adjacent this gap zone to effect the proper transfer ofthe insulation slabs I from the conveyor to position upon a shingleplaced on the platform I8. The mechanism includes a rock shaft 83carried in end bearings 84 upon bearing pads 85 at the upper ends of thevertical members I0. Near one end of the shaft, a timing lever or finger86 has been positioned to project into the path of movement'of thecarrier element 34. A second lever or finger 81, near the opposite endof the shaft 83, projects toward the path of travel of the carrierelement 34, but this finger is somewhat shorter than timing finger 86and is set at a different angular attitude. The intermediate span ofrock shaft 83 carries three working fingers 88 all set at the sameangular attitude and each being aligned with one of the conveyorguide-ways for the insulation slabs. The fingers 88 are at a differentangular attitude relative to fingers 86 and 81, and from a comparison ofthe location of fingers 88 relative' to guides 98 in Fig. 3 with therelative longitudinal spaced alignment of the guides 99 with the severalnotches in plate 26 formed between the supporting lips or surfaces 32,as in Fig. 2, it will be appreciated that each finger 88 swings throughthe end zone of the aligned notch in plate member 26 beyond the adhesivecoating rolls 61. Further inspection of Fig. 5 will reveal that lingers88 pass below plate 26. The rock shaft 83 with its several fingerelements is normally maintained in the full line shown of Fig. 4 bymeans of a counterweight 89 carried by the weight arm 9D, and theangular position is determined by the weight 88 resting on an anglememberul as a stop. Member 9| be further 'described presently inconnection with Figs..1 and 3,.

In cooperation with thev above rockable mechanism, each bar element 34is provided with an upstanding abutment element 92 xed at the proper endzone for travel into engagement with timing finger 86. The opposite endof each bar 34 carries an enlarged abutment element 93 positioned forengagement with the finger 81. Each bar element 34 is provided also withthree spaced notches 94 which are aligned with the respective fingers88,` and' these. notches are in the leading edge so that the fingers 88may enter the same and assume positions of engagement behind theinsulation slabs brought thereto by .the bar elements.

Observe that the full line position of the parts in Fig. 4 illustratesthe normal attitude of the same at theV moment a bar or carrier element34 has advanced so that the abutment element 92 attains contact withtiming finger 86. As the conveyor travel continues, the element 92 rocksor swings the several lingers against the gravity load of counterweight89 to the broken line position, such that the fingers v88 are broughtinto the notches 94 and begin to pick up the insulation slabs. Finger 81and' abutment element 93 are not yet in engagement. At this point, theinsulation slabs I have reached their transfer stage and the leadingmargins are now resting on thetab surfaces of the shingle S supported onplatform I8.

The full line showing of Fig. 5 is still another position of advancedconveyor movement at .the point Where abutment element 93 attainsengagement with the nger 81. Observe that the ngers 88 are now in fullcontrol over the insulation slabs I and have effected an advance thereofahead of the carrier element 34. The broken line showing of Fig. 5,illustrates the final position of the transfer mechanism when theinsulation4 slabs I have been fully transferred to the platform I8 andthe abutment element 93 is beginning to ride downwardly and partengagement with nger 81. Subsequent travel of the conveyor moves thecarrier element 34 through the gap betweenA the .tank 2| and rear marginof the platform I8. In Fig. 2, the platform margin issutably notched at95 and 96 to permit unobstructed passage of thev respective abutmentelements 92 and 93. As soon as element 93 and finger 81 breakengagement, the counterweight 89 drops to the angle member 9| andautomatically restores the mechanism for the next operation` in responseto the carrier element 34 next in line.

The proper assembly of the three insulation slabs I upon each shingle Sis regulated by means now to be described. In Figs. 2 and 3, it can beseen that the shingle platform |8` is provided with a centrally locatedand laterally spaced pair of alignment cam elements 91` which areadapted toguide the center one of the shingle tabs during the placementthereof upon the platform |8. Once this tab is received between thesecam elements 91, the shingle is then pushed toward the rear margin oftheV platform, and is brought to a proper inward position upon abutmentof the opposite wing portions of the shingle with spaced stop blocks 98.At this time the three tabs of the shingle are located above thevertical columns 29 (Figs. 2 and 3). Each shingle tab now lies betweenand below a pair of laterally spaced guide'ns 99 being carried onsupport elements |00 fixed to the platform I8. The guide ns 99 arevertically directed and extend to: the rear margin of the platform I8 sothat the adjacent pairs thereof act to guide the oncoming insulationslabs over the shingle tabs.

The next operation of the present machine is lto exert a compressiveload on the insulation slabs so as firmly to unite the same with theshingle tabs and complete the assembly of the insulated shinglecombination. The means provided to carry out the pressing operationincludesl the transversely directed angle member 9| supported at itsopposite ends upon the upper ends of the vertical extensions of postsI9. This member 9| carries spaced sleeve guides |0|, each locatedcentrally of the pairs of guide ns 99. Each guide sleeve receives avertically movable rod |02, at the lower projecting end of which issecured a platen or pressing plate |03, and the plate |93 moves betweenthe adjacent guide ns 99. The upper end of each platen rod |92 isreceived in a sleeve socket element |94 xed to a common carriage member|95. The rod end portion received in the socket |04 carries a pin |96which projects through a socket slot |01 to prevent angular displacementthereof. Each platen rod |92 is resiliently urged downwardly to thelimit of movement of pin |06 in slot |01 by a spring |08 disposedbetween the fixed socket and a collar |99 on the rod. This yieldableconnection of each rod |02 with the common carriage member |05 permitsthe several plates |93 to assume positions accommodated Ito the slightvariations of insulation slab thickness which normally occurs.

The carriage member for the three press plates |03 is downwardlyactuated from its normal raised position (Figs. 1 and 3) by a pair ofdraw rods |I9 secured to member |05 by suitable collar elements, anddirected .to pass through apertures in platform I8 for similarconnection with a transversely directed draw bar The draw bar I||carries at its outer ends, angle bracket assemblies ||2 which arepivotally connected with respective levers ||3. The pivot connection oflever ||3 with the draw bar III is eiected intermediate the length ofthe lever, as may be seen in Fig. 1. Since there are two such leversII3, the single showing thereof in Fig. 1 may be taken. as typical forboth. Lever |I3 is normally horizontally directed from a pivotconnection at the lower end of a hanger member H4, the latter -beingfixed upon a convenient portion of the angle member I4. The free end ||5of the lever lies adjacent the hub zone of the sprocket 44 on driveshaft 45 and is directed to have contact with a tappet element ||6 iixedin the said sprocket hub. Thus, once in each full revolution of theshaft 45, the tappet element ||6 engages the end ||5 of lever ||3 andpivots the same about hanger I I4 until the lever and tappet eventuallybreak contact. During this lever operation, the draw rods I I0 aredownwardly displaced against the force of restoring springs II1, andthis action serves to depress each of the platens or plates |03. Thispress operation is suitably timed to occur when the insulation slabs Ihave reached or are about to attain the intended position of finalassembly with the shingle S.. The springs IIT act to restore the pressmechanism to its normal position for subsequent operations.

From the foregoing description, it should be clear and obvious in whatmanner the present machine performs the several steps in the productionof insulated shingles. The improvements reside in those individual andcooperative 9 means', parts, elements or sub-assemblies' which arenecessary to the successful operation of the machine. It is expectedthat substitution of equivalent parts may be made herein Withoutdeparting from the scope of the claims hereafter appearing.
